LAYING WOOD.

SPECIFICATION forming part of Letters Patent No. 390,611, dated October 2, 1888.

Application filed December 17, 1887.

To all whom it may concern.-

Be it known that I, HUGH MOHUGH,a citizen of the United States, residing at New Bedford, in the county of Bristol and State ofMz sachusetts, have invented certain new and useful Improvements in Processes for Inlaying, of which the following is a specification.

Heretofore inlaying has been done by first cutting a cavity in the surface of the article to be inlaid and then fitting and gluing theinlaying material therein, or by forcing thin sheets of wood like veneer into the surface of the article by means of dies. The first of these methods is the oldest and most expensive. Thelatter is open to theobjection that heat and moisture eventually throw out theinlaying and destroy the work.

The object of my invention is to produce inlaid work which will be durable and much cheaper, while it is fully equal in appearance to that produced by the more expensive processes described.

Figure 1 of the accompanying d rawings represents a piece ofinlaid work produced by my process, and Fig. 2 represents a view of the same in cross-section.

In both figures aindicates the inlaying matcrial.

In practicing my invention I take the article to be inlaid and apply to it some suitable substanccsueh as rubbing varnish or oil and shel lac-iu order to fill the pores in its surface. I then engrave 0r stamp in the surface of the article the required design or pattern of the work. I then take a plastic material of some kind-such asarnixture of whiting and glue of a nature that will become hard when dry, and fill the cavities of the engraved figure 01" 'a plastic substance composed of whiting and Serial lie T258226. (No specimens.)

desigmwith the samein such a manner that the pl' stic material shall be level with the suro face 0.: the article. In doing this an instrument ike a putty-knife or a piece of soft pine similarly shaped Ihave found to be handy. Aftegthe plastic material in the engraved design is dry and hard I use a cloth moistened in alcohol to clean the surface of the article around and between the inlaying. I then cover the whole surface of the article and the inlaid design with varnish, shellac, or some other suit ble finish.

If I desire the inlaying to be of any particular color, I introduce into the plastic material the proper pigment and mix it thoroughly, so

as so color the whole mass before filling it into 5 glue or other analogous material in such a manner that the surface of the inlaying shall be level with the surface of the part inlaid, then cleaning the surface of the article with alcohol, and finally coating the article and its 70 inlaying with varnish or other suitable finish, substantially as described.

HUGH MOHUGH.
